The Cat in the Hat Knows a Lot About That!

Keep the Beat

Nick and Sally have been running around the backyard and now their chests are thumping along. The Cat explains that this is their hearts booming. A visit to Dr. Giggles, he will answer that question: by shrinking down super small, they follow Dr. Giggles' directions to follow the path that blood takes, learning about how the heart is a pump. They watch Thing 2's heart beat faster when he runs, and slow down when he stops. With all this running around, their bodies are now making another sound: rumbling tummies.
